Cell Type: The type of silicon that comprises a specific cell, based on the cell manufacturing process. Each cell type has pros and cons. Monocrystalline PV cells are the most expensive and energy intensive to produce but usually yield the highest efficiencies. Though polycrystalline and ribbon silicon cells are slightly less energy intensive and less expensive to produce, these cells are slightly less efficient than monocrystalline cells. However, because both poly- and ribbon silicon panels leave fewer gaps on the panel surface (due to square or rectangular cell shapes), these panels can often offer about the same power density as monocrystalline modules. Thin-film panels, such as those made from amorphous silicon cells, are the least expensive to produce and require the least amount of energy and raw materials, but are the least efficient of the cell types. They require about twice as much space to produce the same power as mono-, poly-, or ribbon-silicon panels. Thin-film panels do have better shade tolerance and high-temperature performance but are often more expensive to install because of their lower power density.
Sanyo’s "bifacial" HIT panels are composed of a monocrystalline cell and a thin layer of amorphous silicon material. In addition to generating power from the direct rays of the sun on the panel face, this hybrid panel can produce power from reflected light on its underside, increasing overall panel efficiency.
Cells in Series: Number of individual PV cells wired in series, which determines the panel design voltage. Crystalline PV cells operate at about 0.5V. When cells are wired in series, the voltage of each cell is additive. For example, a panel that has 36 cells in series has a maximum power voltage (Vmp) of about 18V. Why 36? Historically, panels known as 12V were designed to push power into 12V batteries. But to deliver the 12V, they needed to have enough excess voltage (electrical pressure) to compensate for the voltage loss due to high temperature conditions. Panels with 36 ("12V") or 72 ("24V") cells are designed for battery-charging applications.
Panels with other numbers of cells in series are intended for use in grid-tied systems. Due to the increased availability of step-down/MPPT battery charge controllers, grid-tied panel

Misc

Il faudra sans doute 50 a 100W de panneau photovoltaique pour un relai, on trouve du 90W amorphe pour 121 euros livrés :

20kg de batterie (100 euros) + panneau (121 euros) + regulateur (50 ?) + matos wifi et antennes (300 ?) ~ 600 euros.

Une solution alternative :

- un routerboard a la place du switch
- un cable pieuvre power jack 1 femelle vers 8 males
- une alimentation de portable 19V 3.42A
- un splitter PoE passif
- des injecteurs PoE passif

L'avantage du routerboard est qu'il accepte 9 a 28V DC en alimentation donc a peu pres comme les ubiquity et que ses temperatures de fonctionnement sont tres larges de -40 a +55C.
La doc du routerboard n'est pas tres claire sur la taille du power jack est-ce 5.5/2.0 ou le plus standard 5.5/2.1 ?
